Claims.

This invention relates to improvementsjin window sash fasteners for lockin the sashes rtogether' against relative movement, thereby preventing unauthorized opening of the window,nas a safety precaution.

To the attainment of these ends and the accomplishment of other new and useful objects as'will appear, the invention consists in the features of novelty in substantially the construction, combination and arrangement of the several parts, hereinafter more fully described and claimed, and shown in the accompanying drawing illustrating this invention, in which Fig. 1 is a sectional view of the adjacent parts of an upper and a lower window sash, having a sash fastener constructed in accordance with the principles of this invention mounted in place and in an operative position.

Fig. 2 is a horizontal'sectional view'as taken on line 2-2,-Fig. 1.

Fig.3 is a detail perspective view, on an enlarged scale, of the snubber or looking lever.

Fig. 4 is a detail perspective view, on an enlarged scale, of the base plate or supporting member for the locking lever.

Fig. 5 is a detailzperspective view of the pivot pin.

Fig. 6 is a side elevation of the fastener; showing the mannerin which the pivot pin maybe positioned between the base plate and thesnu'b her, to maintain the snubber in an inactive position.

Referring more particularly to the drawing, the numeral i0 designates a base plate -or supporting member which is preferably formed as a light sheet metal stamping having a certain degree of resiliency as is common with most stampings of this nature and having upwardly projecti-ng sides I I, and a downwardly-projecting portion or flange 12 at one end thereof. This supporting member'may be ofany desiredsize and constructedof any suitable material-a longitudinal slot l3 being provided in the plate. Any-number of openings [4 may be provided in the sides ll, fora purpose 'to be later described, and they are preferably in register, respectively, with each other. The upper edges of the sides ll maybe of any desired configuration, but :are preferably inclined, as at 1.5.

A snubber or looking lever I6 is preferably formed with a body portion 'il having downwardly projecting side flanges or portions i8, the body portion ll terminating short of the ends of the side flanges or portions 18 to form aloifurcated portion l9, and a plurality of alined openings'ZU are provided in the .ends of "the side flanges or portions i8 which form thextsidawalls of the bifurcation H3. The opposite endwof the locking flever or snubber I6 is shaped to form an end portion 2| beyond the side flanges-.orportions 1:8, :and extends in a direction opposite to that of the flanges 8. The extremity of'theend portion 2| may be given any desirable shape, but it is preferably 'shapedto form a curveror :rounded extremity ZZQ A :snubb'er pad '23, :such' as rubberor any suitable-material thatwill cause a binding action, may be provided, "which' may be sleeved or otherwise attachedor secured to the extremity'22.

The snubber or looking lever l6 fisattached to the base'plate so that the sides I8 'willfit over the sides H, and a pivot epin 'z l ispassed'through registering holes M and 2.0 of the two members, so that the snubber or'lever will :be pivotally connected to the base member.

Adjacent one end of the pivot pin 24,".there is a reduced 'porti'onT25 which is of a width greaterthan the combined thicknessxof the "side wall I I of the base plate :and'the flange 18p? the snubber or lever I 6 through-which :a-portion The fastener is secured to the upper cross-rail 28 of the lower sash '29 in a position thatthe flange i2 of the base plate will engage the-outer face .of said rail, and is secured in such position bya fastening device, :such .as a screw 30 that passes through the slot l3 :and into the "sash rail 28.. The slot 13 permits of an adjustment of the fastening-screw 30, to .a'ccommodate'sash rails of difierent thicknesses. The pivot pin :is-:also inserted into the registering holes .in .the :base plate and snubber, according to the sizeof'the rail. 28, so that when the 'parts are in position. the snubber pad '23 will rest by gravity against one of the ."upright sides 3! of the upper sash.

ThBIEXtlSBlTfitY 32 of the pivot pin is of such a size :as' :to permit the pin to be entirely withdrawn'or detached, so asto permit it to be inserted into other registering openings I l, 20, according to the size of the window to which this device is applied, and. also to permit the device to be shipped or stored in a knockdown condition.

When the snubbing device is in itsbperative position, .that when the arm 21 is removed from its wedging position between the two parts H1 and It, the arm 21 will rest .bygravity on the sash, rail .28, andthe snubberlfi will rest by gravity against the upright side 3| to effect a snubbing action whenever an attempt is made to raise the window sash relative to the upper sash, while permittin free movement of the lower sash in the other direction. Since the extent of the reduced portion 25 of the pivot pin 24 is sufficiently great so as to permit a certain freedom of lateral movement between the two main parts of the device, when it is desired to render the device inoperative it is merely necessary for the operator to raise the snubber l6 and also rotate the pivot pin 24 about its axis so as to bring the arm 21 into alignment with the V-shaped crotch existing between adjacent sides of the two parts and thereafter, by forcing the pivot pin in the proper direction, the extreme end of the arm 21 will act as a wedge between the two parts and maintain the snubber in an elevated position, as shown in Fig. 6, so that the buffer pad 23 is clear of the upright sides 3| of the upper sash. In this position of the pivot pin 24 and, arm 21 the weight of the snubber I6 restingon the end of the arm 21 will pinch," so to speak, the arm and prevent lateral displacement thereof.

When the arm 21 of the pivot pin 24 is to be positioned between the adjacent edges of the fianges'or sides l8, II, the lever or snubber l6 may be swung about its pivot, so as to move the buffer 23 out of contact with the window frame 3|, by grasping the end 26 of the pin, drawing the same forward and rotating the pin 24 in its bearings to a position that the end 21 may be inserted between the lower edge of the side wall l8 of the snubber and the top edge l of the side wall ll, of the base plate It), by moving the pin backward in its bearings.

While the preferredform of the invention is hereinshown and described, it is to be understood that various changes may be made in the details of construction and in the combination and arrangement of the several parts, within the scope of'the claims, without departing from the spirit of this invention.

What is claimed as new is:

l. A window sash fastener embodying a base plate having upwardly projecting sides, there being alined openings in said sides, a snubber having downwardly projecting flanges provided with alined openings, a pivot pin for swingingly connecting said plate and snubber, means whereby said base plate may be secured to a sash in a position such that a portion of said snubber will engage the other sash, an extension on said pivot pin having an inturned end, said pivot pin being capable of limited axial sliding movement laterally of'the base plate and snubber whereby said inturned end may be inserted between the base plate and snubber to prevent movement of the snubber about its pivot in one direction.

2. A window sash fastener embodying a snubber, means pivotally mounting said snubber upon one of the window sashes, said snubber being adapted to engage and wedge against the other sash, when said sashes are relatively moved in one direction, and means adapted to engage said snubber beyond the pivot thereof, for maintaining said snubber out of its locking position, to permit the sashes to be freely and relatively moved in either direction, the last recited means constituting 'a portion of the first recited means.

3. A window sash fastener for relatively mov able sashes including a supporting member adapted to be secured to one of the sashes, a snubber, a, pin pivotally connectin the snubber adjacent its end to the supporting member, whereby when the snubber engages the other of the sashes, and said sashes are relatively moved in one direction, the sashes will be locked together, said pin being freely movable axially and relative to said snubber and member, said pin being formed with a reverse bend therein, theextreme end of the reverse bend being capable of entry into the space existing between said snubber and member to maintain the snubber elevated by a wedging action to thus render the same inoperative.

4. A window sash fastener for relatively movable sashes comprising a supporting member adapted to be secured to one of the sashes, a snubber, a pivot pin extending completely through said supporting member and snubber and serving to pivotally connect the snubber to the supporting member whereby an upper surface of the supporting member and a lower surface of the snubber may assume different angular positions relative to each other and whereby said snubber may rest by gravity upon the other sash to prevent relative movement between the sashes in one direction while permitting such relative movement in the other direction, one end of said pivot pin exteriorly of the supporting member and snubber bein bent laterally of the pivot pin and having a reversely extending end substantially parallel to the pivot pin, said pivot pin having limited freedom of movement axially and relative to the supportin member and snubber whereby said reversely extending end may enter the space existing between the snubber and supporting member to maintain the snubber elevated and out of contact with said latter sash or be withdrawn from such space to permit free tilting movement of the snubber on said supporting member.

5. A window sash fastener for relatively movable sashes comprising a supporting member adapted to be secured to one of the sashes, said member being substantially U-shaped in crosssection and provided with upstanding parallel sides, a snubber likewise substantially U-shape in cross-section and having downwardly extending parallel sides, there being a series of aligned openings in the sides of said supporting member, there being a series of aligned openings in the sides of said snubber, said openings bein arranged in pairs and the openings in the sides of the snubber being designed for selective register with the openings in the sides of the supporting member, a fastening device comprising a member including an elongated pivot pin portion adapted to be passed through the selected registering openings in the sides of said supporting member and in the sides of said snubber to pivotally connect the supporting member and snubber toe gether along a selected transverse axis, said snubber being adapted to rest by gravity against the other sash to effect a snubbing action thereon when one of said sashes is moved relative to the other in one direction only, said pivot pin portion being formed with areduced portion of an extent in excess of the combined thickness of adjacent sides of the supporting member and snubber, said reduced portion being adapted to be placed in registry with the openings in adjacent sides of the snubber and supporting member to permit limited axial movement of the pivot pin portion and consequently of the fastening device relative to the supporting member and snubber, said fastenin device including a lateral extension on said pivot pin exteriorly of the supporting member and snubber and a reversely turned por-' 2,554,455 5 6 tion at the end of said lateral turned extension, REFERENCES CITED the extreme end of said reversely turned portiqn The following references are of record in the being movable from a retracted position wherem me of this patent: it lies wholly outside of the space existing between said snubber and supporting member to an 5 UNITED STATES PATENTS advanced position wherein an end thereof occu- Number Name Date pies a position between said supporting member 332,170 Stoler Dec. 8, 1885 and snubber to effect a wedging action between 766,322 Butcher Aug. 2, 1904 the supporting member and snubber to maintain 847,345 Leach Mar. 19, 1907 the latter elevated and out of contact with said 10 1,164,724 Kilmer Dec. 21, 1915 latter sash. 1,439,260 Pruell Dec. 19, 1922 CHARLES L.
